The Assembly authorities have issued guidance on how a failure to nominate a First Minister would eventually lead to a new election. Carwyn Jones remains in post for now -he serves "at Her Majesty's pleasure" but AMs have 28 days to either nominate him once again to the Queen or put forward somebody else. The 28 days began on polling day -May 5- and end on June 1.

The First Minister of Wales is the leader of the Welsh Government and is appointed by Her Majesty the Queen following nomination by Assembly Members.

A First Minister must be nominated by the Assembly within 28 days, so by the end of 1 June 2016. The First Minister is nominated by the Assembly and the nomination is submitted by the Presiding Officer for Her Majesty Queen Elizabeth's approval. She is responsible for appointing the First Minister. If a First Minister isn't nominated within 28 days of the election, another Welsh general election must be held.

The Presiding Officer, following consultation with the political parties, will notify Members of the date and time of the next Plenary meeting, where another vote by roll call can take place.

Questions to Welsh Secretary Stephen Crabb in the House of Commons have been postponed so that MPs can pay tribute to the Queen instead. He was due to answer Welsh questions on Wednesday, the day Her Majesty becomes Britain's longest-reigning monarch.

I have agreed that questions to the Secretary of State for Wales should be postponed from this Wednesday until the following week, Wednesday September 16, to allow the House to mark the occasion on which Her Majesty the Queen will become our longest serving monarch. Prime Minister's Questions will take place as usual afterwards at 12 noon.
